Just to be sure - you run commands *inside* menuentry { ... }, right?
If you run them exactly as they appear below, it just (re-)defines menu
entry without actually booting anything.

You need to run commands inside of curly braces, followed by
"boot" (which is implicit in case of menu entry processing).
